Abstract (en)
The invention relates to a method of manufacturing a body in which of a folded metal plate having an opening tear terminating in a tongue, overlapping edges are welded together, characterized in that at the opening tear the welding intensity is decreased as such that either solely tin-melting occurs so that at the opening tear the edges are linked by melted tin, or welding is interrupted and thereafter a slot formed at the opening tear between the overlapping edges is covered using a sealing material. <??>Further the invention relates to a metal plate having an opening tear formed by two weakening scores extending traverse to its edges and terminating in a tongue, characterized in that at the opening tear one of the edges is provided with a covering- and or oxide layer which has a relatively smaller electrical conductivity, to the body manufactured and to a container comprising same.
